Abstract

A pump in which a vibration element vibrates at high degree of efficiency to make the pump perform a highly efficient pumping action to discharge a large amount of fluid. The peripheral edge of a diaphragm (3) is fixed to a housing (2) to form a pump chamber (5) between the diaphragm (3) and the housing (2). A piezoelectric element (4) fixed to the diaphragm (3) drives and flexurally vibrates the diaphragm (3), changing the pressure in the pump chamber (5) to send fluid, such as air, under pressure. A circular node portion (6A) occurring when the vibration element (6), including both the diaphragm (3) and the piezoelectric element (4), vibrates at a natural frequency is elastically fixed to the housing (2) via an elastic adhesive agent (40).
